How the location of Kush influnced?

Answer 1

After king Kashta ("the Kushite") invaded Egypt in the 8th century BC, the Kushite kings ruled as Pharaohs of the Twenty-fifth dynasty of Egypt for a century, until they were expelled by Psamtik I in 656 BC. During Egypt's Middle Kingdom period (1991 - 1786 B.C.E.), Kush became a vital trading center between Egypt and Central Africa. Kush had a wealth of natural resources that were unavailable in Egypt, such as gold, iron, and leather. To obtain these goods, Egyptians traded items such as grain, beer, and linen. Kush also served as a stopping-off point for goods sent from Central Africa to Egypt, such as ivory, timber, and slaves. During the New Kingdom period, Egyptian pharaohs conquered Kush several times in order to protect their trade routes. They also forced Kushites to pay them a tribute of valuable items each year as a sign of continuing loyalty.
